Abstract

A windshield washing system, especially for motor vehicles, is provided with a wiper shaft, on which a wiper arm can be non-rotatably fastened and which wiper shaft includes an axial bore in order to receive a line made from form-stable plastic material with at least one channel, through which at least one washing nozzle moving in pendular motion with the wiper arm during the wiping process can be provided with washing liquid. In order to ensure that the wiper shaft takes along the line, the line is form-fittingly connected with the wiper shaft in the swivelling direction of said wiper shaft at the end of the wiper shaft turned away from the wiper arm.
